Sales growth in Q2 mail-order pharmacy sales, based on orders placed on Drugstore.com or through its call center, reflected an 11% year-over-year increase in the number of orders to 127,000 as well as an increase in the average value per order. Average order value rose along with a 5% increase in pharmaceuticals and a tendency for customers to order quantities of 90 days or more, Drugstore said.

Drugstore reported earlier this month that overall Q2 net sales rose 10% year-over-year to $96.9 million from $87.8 million. Drugstore, which is ranked No. 28 in the Internet Retailer Top 400 Guide to Retail Web Sites, had 2004 sales of $360.1 million.

Drugstore also reported in a statement filed Monday with the Securities and Exchange Commission that San Francisco investor J. Carlo Cannell, managing director of Cannell Capital LLC, has acquired about 4.7 million shares of Drugstore.com Inc. for stake of about 5.1% of the retailer’s outstanding shares. The investment is worth about $16.4 million, based on Drugstore’s closing stock price last Friday of $3.49 per share.
